Targetfollow looks to the past to safeguard the future in its Duke's Wharf development

Targetfollow is interested in putting a modern spin on an environmentally friendly technique which was first used almost 70 years ago.

At our Duke's Wharf site - hopefully set to see 150 new residential units plus offices, built on the riverside site in the heart of Norwich - we would like to use a water source heat pump to both heat and cool the properties.

It will be in exactly the same spot used by Norwich City Electrical Engineer John Sumner when he installed Britain's first commercial water source heat pump in 1946. He created a pump, made from scrap and a 24-year-old compressor, to heat the same five-storey building and reduced heating costs from traditional methods such as electricity or solid fuel, by two-thirds.

His forward-thinking ideas gained worldwide interest - especially when the river froze and yet the building was still nice and warm!

The technology, which is basically a fridge in reverse, uses free solar energy stored in the waters of the River Wensum to produce heat rather than power.

Heat Water Pump

Heat pumps are low-tech and have a long life of 20 years plus, much more than conventional boilers. Using river water as the energy source is more reliable than the air (where very low temperatures can be a problem) or the ground (where initial capital outlay can be high, combined with the potential for depleting the ground's heat).

It is hoped that the development, set to start on site early in 2015, will be classed as zero carbon (in terms of its operation). This would be achieved by purchasing the remaining electricity from a 'green' supplier.

Targetfollow CEO, Corin Thoday, said: "This is a very exciting opportunity to promote both the city's engineering heritage and its sustainable future. Targetfollow is committed to sustainable urban regeneration, and we expect this to be the greenest development to date in Norwich."

The scheme is aimed to be on site early in 2015 and, despite minimal marketing, Targetfollow is already receiving expressions of interest from potential occupiers.
